Product description

More about the series Gran Turismo...

The Gran Turismo refractor is an apochromatic triplet with FPL-53 element for maximum colour purity and high contrast! A lens telescope that is versatile and leaves nothing to be desired.

  • Visual observation: Equipped with an optional diagonal mirrors, this apo allows you to observe the moon and planets with the highest possible contrast. The fast apo also allows for long-term observation of difficult deep sky objects such as star clusters, galaxies and nebulae. The crisp star images make observing and resolving globular clusters a real pleasure.
  • For astrophotography, several image field flatteners and focal reducers (flatteners/reducers) from William Optics are available. Equip your Gran Turismo with a guiding scope that can serve as a finder or guide scope. The guide scope rings are already included in the scope of delivery. The Apo is designed for photographing deep sky objects with full-frame cameras.
  • The low-profile 3.3" R&P focuser has a long focus travel and a RotoLock clamp that centres cameras and accessories. An adaptor for 1.25" eyepieces is also included.

The very robust Gran Turismo 103 Apo is really well suited for travelling and for mobile astronomy and astrophotography in general. Take the Apo with you under a dark sky and discover the best objects from the Messier and NGC catalogues. The telescope is uncomplicated, stable and, after its first light, will be your new favourite telescope!

Another special feature of the new William Optics apochromats is the specially calculated Bahtinov focusing mask:

These new focus masks made from optical acrylic glass provide 92% transparency.

The imprinted pattern provides a diffraction structure which is around three times brighter than classic metal masks. The acrylic glass masks therefore produce a clearer diffraction pattern and enable focusing with the help of fainter stars.

It not only matters which telescope you buy but also where you buy it. Our additional services:

  • We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
  • We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
